While there isn't an API method exposed for directly deleting a Route 53
RecordSet (it's performed via POST that acts more like a PATCH than
anything
else)[http://docs.aws.amazon.com/Route53/latest/APIReference/API_ChangeResourceRecordSets.html],
CloudFormation can have templates which contain RecordSets which refer
to zones that don't exist inside the template. Ergo, we need a way to
effect a delete upon these RecordSets when we don't have a direct
reference to the zone.
This exposes a delete method that isn't hooked up to any response (and
rightfully so), it just enables the ~polymorphic deletion behavior that
we've written into the CloudFormation implementation.
